🔍 Key Concepts

• Relationship between the camshaft and crankshaft in an internal combustion engine • Common methods of mechanically transmitting rotation between shafts at fixed speed ratios • Which components listed are valve train actuators versus actual drive mechanisms

💭 Think About

• Ask yourself: which option could realistically connect the crankshaft to the camshaft and keep them in precise timed rotation? • Which of these choices are parts that move valves up and down, and which are parts that actually drive and synchronize other rotating parts? • Think about which systems are commonly used on automotive and small diesel engines to drive the camshaft besides direct gears.

✅ Before You Answer

• Identify which items are valve train elements (that act on valves) and which are power transmission systems (that transmit rotation). • Make sure the method you pick can maintain accurate timing between crankshaft and camshaft over many revolutions. • Eliminate any components that normally do not connect directly between crankshaft and camshaft.
